To @ZZ autom it may concern:

Be it known that we, Cani. RICHARD Jannnnns and lidonssrii "szene, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, ha". invented certain new and useful Improvements in Forged-Steel Draft-Rigging A.tiiiclii'iieiits, ot'bwhich the following' is a specification, reference being had to the aceoniiianying' drawings, and to the reference chaimters marked thereon, which form a part of thi specification. l

This invention relates to draft rigging for railway cars, and has for its object, more particularly, the construction or means for securing the rigging to the car sills and to the car coupler and to the draft gear or shock absorbing iinit, whereby a more perfeet action ot' the latter is secured.

Another object is to produce a draft rigging of such construction as to permit its several elements to be made of forged steel. Another object is to construct the several parts in such fashion as to permit them to bc readily assembled and then held together by lugs and by an inserted key or bolt. Another object of the invention is to construct the parts so as to withstand themaxiinuin of shock and reduce the wear which would otherwise follow, thereby prolonging the period of utility of the device. i

To the accomplishment of these and other objects, the invention consists in the devices and combinations of devices illustrated, described Aand clainied herein.

In that form of our invention in which we have chosen to illustrate it, in the accompanying drawings:

Fig. l is a top plan view of our invention, as applied to a pair of conventionally shaped and disposedl car sills, detached from the car structure. "i

I `ign2 is a side elevation of the same,`look ing from a plane inside one sill toward the other sill, with some' of the parts in section.

Fig. 3, is a front elevation, on a reduced scale, looking-towards the car end on the line indicated at 3-3 in Fig. 2.

Fig. 4C is a horizontal, sectional view, taken in the plane of the line 4.--4 of Fig. 2. Fig. 5 is a longitudinal, sectional view of the yoke head meinbe. taken on v .c O Flg.2i

Fig. 6 is a transverse, verticai, sectional,

view of one of the yoke heads.

secured at its two the plane of the linev Figs. 7, 8 and vQ are side, top plan and front end views, respectively, of the yoke.

In said drawings, A, A represent a pair of draft sills foi' a car structure, bein of standard channel .section and exteninfr longitudinally of the car in spaced apart, parallel relation; B, B represent front draftgear stops; C, C the opposed or back draft gear stops; D a shock absorbing-unit or draft geen as a wliole;,E the shank of the oar coupler; F, a strike plate unit upon theend beam or channel G of the car structure; H the yoke heads; K, the draft key or pin, and Y is the yoke.

The strike plate F is ofthe sills A, to the channel G, by rivets 1 as shown in Fig. 3. l,A strap member 2, riveted at its ends to the channel G and to the lower anges 3 of the sills A, forms a suitable support for what we term acarrying iron et for the coupler shank E. The iron 4 in this instance, is bent up at its ends to tit within the sills A" and is riveted at 5 to the strap 2. y

The front draft-gear stops B, B, are secured to the inner or proximate faces of the sills A, A, by rivets 6, and the opposed stops C' similarly seured to the sills by rivets 7. Intermediate these pairs of stops is a transversely disposed carrier strap 8 ends by rivets 9 to the secured transversely lower ianges 3 of serving as a. support or carrier upon which the draft gear unit D may rest and be supported. The carrier strap, in this instance, has a central, transverse depression or oii'set 10 to accommodate one arm of the yoke Y between the strap 8 shock vabsorbing unit D may be of any con ventional type and since, per se, it forms no part of the present invention except in oombination, as a unit, with the other elements of our invention,it is not necessary to illustrate or describe it in detail. The illustration given may indicate a type of construction such for example, as that shownin the Christy Patent No. 1,263,374, of April 13, 1918, where the housing is hollow and contains springs acted upon by triangularly shaped wedges 11,`whioh oontactwith a follower plate-` 12, .the latter shoulders 13 of the front stops B, and the end ot' the housing of theunit D resting against the shoulders 14 of the back stops C. It

the sills A; 'said strap 8 resting against the and the unit D. The

" will be understood that. there isA relative movement between lthe parts, both on the draft and bud", the follower plate 12 and wedges liheing pushed toward the unit D on the bud and the unit'D traveling' lon itudinally' towards the wedges under drat of the coupler yoke.

Referring now more particularly toFigs. '7, 8, end 9, it 'Wiii henoted'` that the coupler yoke Y 'is i-sheped, having two long arms iunited by an end member 16 and that. 'the free endsof the arms have a head of pe.-

euliar conformation, being both thicker and I AWider than the thickness and Width of the arm '15.' The yoke head and the yoke ends have compiemental 'engaging parts which may he somewhat modified from the forms illustrated. As shown, each head has a raised Hangs 17 which extendsacross the Width of theyok'e arm 15, its inner'fa'ce being recesseo 'between its two straight ends. Thus on wi et. may be termed theA inner or draft. gear L' sidi his central V-shaped ange has suingV rib.

` tapered pistes ofgr 'a bearing er ulder 18 and a straight hearing shoulder 19. at each end of the reeessed'part,

each of seid shouiders 18 and 19 having av parallel with the' surfaces 19. When a iiler plate (indicetedhy dotted lines in Figs. I and 8) is used between" the end 16 of the yoke and the endof the housing of the unit. D, it, may he Secured to the yoke by ai rivet passed through the aperture 24 in the end 16. The Vfrom'. 'draftv ar stops B, B, are

aiail'y increasing thickness, terminating in e' raised, transverse shoulder 13. Extending centiuliy from one end ofthe stop and substentiaily at right ungies to seidshouldenis' a. raised strength rough the ta red plete B and its rib is an elongated s ot or' aperture ada ted to ree/sive a draft key K. Tieopposed or rear draft gear stops C nre taperedpiates which gradueiiy increase in thiemess ,toward their liront ends; the

' front ieee or shouider fili o ssid'stops hef ing straight. and vertiealiy disposed to receive the end of the gear unit. D.

The two yoke heads H are required, one for each side of the coupler shank. The

` headsere each provided with surfaces coinpieme'ntai in conguration to surfaces on the end of the lyoke arms 15, so that when they are placed in position on each side of the `volte, the oke arms .and heads are firmly interlooke the `lugs on the' yoke head being on the top and thebottom surfaces of the yoke arm. The hey Kia passed horiiaonteiiy the distance' between t misses a larger'frictional surface hearing upon the housing of the draft. geary unit D, which is an important practice! feature of the inveneferring to Figs. 5 and 6, more articularly, it will be seen that the .he H has a straight'body portion 38, provided at top and bottom with inturned Harige `members' 39, whichv latter, when the'l ports are assembied, extend above and' below -the'yoke ends and contact. withlseid yokel ends. 'The back margins offthe angemembers 39 are straight' and are adapted to beer against the front straightsurface of the yoke lug 22, as CearIyseen in Figs. l and 2;' while their front. faces or mar insinciine downwardly from the body as iiiustrated, to iii'. within the 'be-erin shoulder '18 of the yoke iange 1'?. The updy part. 38 ispro` vided at its freni; with a forwerdly ing, thickened and apertured retaining ing or arm 41,' which -isbraeed by and united at its side margins with the body part' 3S 'by strengthening wehe 4&2. The aperture 43 which extends `through the arm di conforms in shape tothe aperture? oi'tthe sto B, though it is not so-iong. The key tits snugly vin the aperture 43, as shown' in Figs. 2 and 4, and is of a lenh sueient to span e sills A, passing through as it does, .the two sills, the front, stops B, B, the olrefheads H, H, and the yoke shank E, t e latter and the siilsheing suitably apertur'ed for lthe purpose. The key K has va anged heed 44 et one end and at the other end is provided with a washer' d5 held in pier/e 'by' a Cotter pin 46 nich passes through'en aperture 47 in the het' K.
